What is the length of the sub-floor?

Question

Stan is purchasing sub flooring for a kitchen he is remodeling. The area of the floor is 180ft. to the 2nd power and the width of the kitchen is 12 ft. What is the length of the sub-floor?

Answer 1

The area of a rectangle is:

 

Area = Length x Width

 

The Area is given as 180 square feet (ft²) and the width is given as 12 feet.  Let's plug those values into the Area formula to find the length:

 

Area = Length x Width

180 = Length x 12

 

Divide both sides of the equation by 12:

 

180/12 = Length

15 feet = Length
